Appendix 1. Sampling Unit
K9424GA Sampling Unit for OX100/102
This sampling unit is designed for the OX100 Series Oxygen Analyzers when they are
used where a sample gas contains a small amount of organic solvents (isopropyl alco-
hol), such as in reflow furnaces.
The sampling unit comprises two membrane filters to eliminate dust and mist, a suction
pump to draw a sample gas, an activated carbon filter to eliminate organic solvents, and
a flowmeter to monitor sample gas flow rates.
Notes
If repair is required, the is equipment will need to be returned to the factory. For repair
or maintenance, contact your Yokogawa representative.
